According to a NordicHardware report, December 5 is pin-pointed as the day AMD will unveil its some of its new Radeon HD 7000 graphics processors. It is indicated that products launched on that day will be based on GPUs built on the 28 nanometer fabrication process. The new products will be unveiled in London. It's likely that these are mobile parts based on the "Thames" and "Seymour" silicons. An alternate theory is that AMD could unveil some of its next-generation GPUs based on the GCN architecture, AMD's biggest leap in GPU architecture since Radeon HD 2000 series.
